Troubleshooting
Round Cardamom problems — and how to fix them
Round Cardamom (Amomum compactum) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root rot from poor drainage
Despite needing permanently moist soil, standing water in poorly draining compost causes anaerobic conditions and rapid root rot. Always use a deep container with large drainage holes and a structured, open compost rather than a dense peat-based mix.
Scale insects
Warm, humid growing conditions suitable for Amomum compactum also favour soft scale insects, which cluster on stems and leaf undersides, excreting honeydew that leads to sooty mould. Check stems regularly and treat with horticultural oil or insecticidal soap.
